Gas door

[MT65]

Has anyone seen this setup before, a gentleman sent me these pictures several years ago when we were discussing relocating the fuel filler. I found these a week ago and thought to not reinvent the wheel, he said it went well, however my geometry is not for s..t, making each piece and testing through that hole is not going well, I must be missing something. I am hanging up on the lower part of the light trim , just as it pivots out of the hole...?..
